vide an oil circulating system for engines,

more particularly "for internal combustion motors, that is simple, direct and reliable, that will distribute an equal quantity of oil to the several divisions of the crank cham her, and that will give visual evidence ot'the proper working of the several divisions of the system.

The invention possesses other advantageous features that, with the foregoing, will be set'forth at length in the following description, wl'1erein I shall outline in full that formotv the invention selected for illustrationin the drawings accompanying and forming part of the present specification. The novelty of the invention will be included in the claims succeeding said description. restrict myself to the disclosure made by said drawings and description, as I niay adopt many variations Within the scope of my invention as expressed in said claims.

In the drawings: Figure 1 is an end elevation of the invention applied to an internal combustion motor. The crank case i broken away below the line 11-11 to disclose the pump in full lines. Fig. 2 is a plan view from above of the lower half of the crank case below the line II-II disclosing the various oil conduits, Fig. 3 is an enlarged detail in front elevation of the conduit manifold. Fig. 4 is a plan view from above of the distributer with the top plate removed. Fig. 5 is a vertical cross section of the same taken on the line V. .Fig. 6 is. a side elevation partly in'cross section of the oil' pump bracket.

I In detail'the construction consists ofv the oil reservoir or sump 1 attached to the bottom of the cranh- The oil pump 3 is in a hollofihtacket d that is herincased: v metical y attached to the-crankcase. The

cored opening 5 leads from the discharge port of the pump and registers with the cored conduit 6 in the well of the crank case. The pump is gircfcrably of the gear this manner the circulation From this it is apparent that I do not.

type, wherein two enmeshed gears are inclosed in" a tight casing. 'This casing is provided with an inlet port on the approach ing side of the gear enmeshment and a discharge port on the receding side of the en- 'meshment whereby the oil drawn into the casing through the inlet port is discharged through the outlet port. One gear of the pump is driven by the vertical shaft 7 eX- tending through. the stufling box 8 and has the spiral gear 10 fixed thereon, enmeshed with the gear 11 fixed upon the cam shaft 12 of the engine. At high engine speeds the pump handles more oil and vice versa. In

' I of oil is proportioned to the engine speed.

By submerging the pump in the oilfprim ing is constantly maintained; By driving the pump with a vertical shaft extending upward through the crank case, thedrive mechanism is simplified, well lubricated, and

wear of the parts minimized. The pump ineludes the inclosing casing 14, surrounded by the depending wall 13, closed at the top. The inlet port opens within the wall and the discharge port passes through thiswall and extends upwardly through the bracket 4. The above recited pump mechanisms are cast integral, the bracket having the cored conduit 5. The pump gears are assembled in a the inclosing casing and sealed by the cover 15 provided with the stufling box 8. The attaching flange 16 on the bracket is faced 951d fits a faced surface on the crank case sun rounding the conduit 6 cored in the we of the. crank case. This conduit leads upward and forward to the end of the crank case and is faced to; receive the manifold 17 bolted thereto. .The conduit 6 registers with the port 18 in the manifold. The oil pumped into the manifold through the port 1L8 passes upward through the-division 19- and the tube 20 and into the feed chamber 21 in the distributor 22. -The distributor consists of a box like structure preferably an integral casting. 1 The dist'ributer is divided into compart-Q Ihents 23, 24:, 25 and 26;- cach of these compartmcnts is connected by the passages 27,

'28, 29 and 30, terminatingat the wall 31 of,

notched'at 32, 33, 34 and 35, to permit an 110 overflow of the oil in the chamber 21 into" each oi t11d compartments. The notches partments the oil drops into the lower compartments 40,41, 42, and 43, respectively connected by the tubes 4A, d5, 46 and 47 with the divisions 48, 49, 50 and 51 in the manifold 17. The latter are provided with the outlet ports 52, 53, 54 and 55, having the tubes 56, 57, .58 and 59 screwed therein and respectively terminating in the several divided wells 60, 61, 62 and 63 of the crank case. The crank case is provided with the longitudinal conduit'blr cored therein. The overflow pipes 65 extend upward from the conduit 64 Within each oil Well of the crank case. Each pipe rises to the predetermined oil level of the crank case. The excess of oil overflows through the pipes 65 into the conduit 64 and returns through the outlet 66 back into the sump.

Having thus described this invention, what is claimed andv desired to be secured by Letters Patent is: A

1. An oil circulating system comprising a sump, attached to a crank case divided into separate Wells, a pump mounted in said sump and geared to the engine shaft, an oil outlet leading from said pump to a manifold, a feed tube connecting said manifold and a distributor, compartments in said distributor fed by a notched overflow wall in said distributer, tubes connecting said compartments with said wells m the crank case,

and overflow pipes leading back to the said sump.

2. An oil circulating system comprising a crank case divided. into separate Wells, a sump connected to said crank case, a pump mounted in said sump, a conduit formed in said crank case leading from the pump to 1 a manifold, a feed tube connecting said manifold. with a feed chamber of a distributer divided into compartments, overflow notches in the division wall between said chamber and each of said compartments, tubes leading from said compartments to said Wells, overflow pipes insaid Wells leading back to said sump.

8. An oil circulating system comprising a crank case divided into separate Wells, a

4 sump connected to said crank case, a pump mounted in said sump in a hollow bracket attached to said crank in register with a conduit formed in said crank case,.a maniv fold connected to said conduit and discharging into a distributer having return tubes leading back into the several divisions of the manifold, discharge tubes connecting said manifold divisions withthe separate wells of the crank case, and overflow tubes in said Wells leading back to said sump.

4. An oil circulating system comprising an engine crank case divided into separate Wells, overflow pipes in said Wells discharging into a sump, a pump mounted in said compartments discharging past ,a sight glass.

into a manifold, divisions in said manifold discharging into the said separate Wells.

5. An oil circulating system comprising an engine crank case divided into separate Wells, overflow pipes in said wells discharging into a sump, a pump mounted a said .sump and geared to theengine wit in the t'valls of crank case, a conduit cored in the said crank case and'leadmg from said pump to a division in a manifold bolted to the crank case, a tube leading from said division to a feed chamber in a distributor, compart- ,ments in the distributor divided from said feed chamber by a wall, notches in said Wall between each compartment and the feed chamber, an opening in each of said compartments discharging past a sight glass into a manifold, divisions in said manifold, tubes leading from said divisions to the respective wells in the crank case aforesaid.
